Tips for Best Results

Portrait Photo:

• Neutral background is ideal (can remove background first with Background Removal)
• Eyes open, looking roughly toward camera
• Good natural lighting, avoid harsh flash
• At least 512×512 resolution

Audio:

• Studio or near-studio quality is ideal
• Clear enunciation
• Minimal background noise
• Keep pauses natural (the avatar will pause movements to match)
